My was having trouble idling fluctuating from 300 to 1000rpm. Then wont start all together. New plugs, cap rotor, plug wires, coil, and now new ignition control module (116$ ouch). I have 10lbs fuel pressure out of the filter (yea bought a tester for that too) have lots of spark out of the coil, have spark at the plug, but it looks week, but it is there. I am out of ideas, still no start, Please help.

Sir-your fuel pressure is way too low-it should be 34psi while idling and w/o vacuum to the pressure regulator should read 43psi-check the fuel filter/intank pick-up sock and fuel pump

Thank you for your responce, actualy, my fuel pressure tester only went to 10lbs, but when I tested it it pegged the gage, and blew off the connector. And with the sparkplug out I smell fuel while I try to start it from the hole. I am welcoming any ideas.

Get a fuel pressure gauge that will read your fuel pressure and get back with me
